Git is very powerful and I do like it more than SVN, but I felt like I had more trouble switching to it from SVN than if I had learned git from a clean slate. Switching my mindset from SVN-style centralized repos to decentralized git was the hardest part, as certain things in SVN didn't translate to git. Git is simple, but switching is not.
There true, it's hard to transform the concept in SVN/CVS to git world.
I remember when I was migrating from CVS to git, it's ok to understand cvs update is git fetch & git merge now, committing is the same, additionally I need to push the commits to share with co-workers. The hardest part to understand rebasing and branch management. But it worth to learn all these concepts, it make version control more flexible. It's pretty cool to use git reset and git push -f to modify the commits history (make sure you know what you are doing).
